It is well known that there are some distributional patterns of houses in rural areas. This paper presents a method which explain the patterns by Morishita's I_δ and potential model, and applies the method to actial data of observations. The results are as follows. The models are effective method which explain the difference of distributional patterns. In case study, Saga-district is presented as concentrated type by Morishita's I_δ and presented as pulled type by potential model. The difference of concentration is showed by I_δ and parameter (α, β).
